摘要
We study the incoherency problem of the indirect translog demand system in which nonnegativity constraints on all goods are explicitly taken into account. Two examples illustrate the nature of the problem: The set of constraints which are binding is not always uniquely defined, and thus the model may not have a reduced form. We derive sufficient conditions for coherency which are related to regularity properties of the demand system; these conditions appear to be 'almost necessary' for regularity. © 1990.
